LISTINGS & APPROVALS
(107°C) maximum temperature rated sprinkler located in accordance with its Listing may be used.
Solvent cement joints shall be made with TFP-500 or TFP-600 One Step Solvent Cement.
Concealed Installations (C-UL)
• In accordance with the C-UL Listing, protection shall be provided for TYCO CPVC Pipe and Fittings. The minimum protection shall consist of either one layer of 9,5 mm thick gypsum wallboard, one layer of 13 mm plywood, or a suspended membrane ceiling with lay-in panels or tiles classified with respect to surface burning characteristics having a mass of not less than 1,7 kg/m2 when installed with metallic grids. The effectiveness of this protection can be impaired if penetrated by large openings such as ventilation grills, exhaust fans connected to metal ducts serving washrooms excepted. Where such penetration is present, individual openings exceeding 0,03 m2 but not exceeding 0,71 m2 in area must be located such that the distance from the edge of the opening to the nearest sprinkler does not exceed 300 mm.
In these cases any Quick or Standard Response, 107°C maximum temperature rated sprinkler or Listed Residential 107°C maximum temperature rated sprinkler located in accordance with its Listing may be used. TYCO CPVC Pipe and Fittings shall not be used where such openings exceed 0.71 m2 in area.
Solvent cement joints shall be made with TFP-500 or TFP-600 One Step Solvent Cement.
Installation in Concrete (UL & C-UL)
TYCO CPVC Pipe and Fittings are acceptable for use embedded in concrete. Direct contact with concrete does not have any adverse chemical effect on BLAZEMASTER materials. The following installation practices shall be followed.
• As the TYCO CPVC pipe is laid out it shall not come into contact with sharp objects or edges, such as rocks, metal, or structural members. Any open pipe ends shall be protected from debris or concrete getting into the system.
• When laying out TYCO CPVC pipe it is best to use straight runs of pipe. However, CPVC pipe is inherently ductile and it is possible for CPVC pipe to be snaked when it is laid out. This can be useful in some installations when some offset from a straight run can be helpful in avoiding various construction obstacles. Straight runs of pipe will minimize any stress that is exerted on the pipe. When the pipe is embedded in concrete there is not opportunity to relieve any stress once the concrete is poured. Therefore, it is important to layout the piping such that the stress is minimized from the time of installation. (Refer to Pipe Deflection section for allowable deflection.)
• Avoid the contact of TYCO CPVC Pipe and Fittings with construction materials that are incompatible with CPVC. Verify the suitability of a product for use with CPVC with the manufacturer of the chemical additive to confirm chemical compatibility.
